Filed May 6, 1957, st. No. 657,423 4 Claims. (til. 263--1ll5) Thisinvention relates to an operator for swingably mounted windows,ventilators, and the like. The main objects of this invention are,

First, to provide an operator for swingable windows, ventilators, andthe like which is relatively simple in structure and may be compactlycollapsed.

Second, to provide an operator for windows, ventilators, and the likewhich may be merchandised and easily installed as a unit.

Third, to provide an operator having these advantages, most parts ofwhich may be formed as stampings and are economically produced andassembled.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined and pointed outin the claims. A preferred embodiment of the invention is illustrated inthe accompanying drawing, in which:

FIG. 1 is a fragmentary vertical section of a window as sembly embodyingthe invention, with the window open.

FIG. 12 is a view in section on a line corresponding to line 12-42 ofFIG. 11.

FIG. 13 is a fragmentary elevational view of a window sash with theregulator attaching bracket mounted thereon.

In the accompanying drawing, we have illustrated the invention asapplied to a window of the awning or horizontally swingable type, thatis, one which is hingedly mounted at its upper edge. It is desired topoint out, however, that regulators embodying the invention are welladapted for use in various types of windows, ventilators, and the like.It is particularly desirable for use in connection with windows owing tothe fact that it is 3,098,647 Patented July 23, 1963 "ice compact andattractive in appearance, and is very easily operated.

The embodiment of the invention illustrated comprises a supportincluding the base member 1 and top member 2 which coact to provide ahousing for certain of the operative parts. The base member 1 isdesirably formed of sheet metal stock and has upwardly offset laterallyspaced arm supponting portions 3, its end portions 4 being adapted to besecured to a window sill or other support as 5 by screws or othersuitable fasteners 6, holes 7 being provided for the fasteners. The topmember 2 has a central upwardly oifset portion 8, its end portions 9being disposed in parallel relation to the portions 3 of the base. Theheaded actuating arm bearing members 10 also serve as rivets connectingthe support members, the members 10 being provided with shoulders 11 andhaving upset portions 12, as is illustrated in FIG. 7.

The base member 1 is provided with upturned flangelike bearing members13 having bearing openings 14 therein for the shaft 15 of the worm 56which is disposed between the base and top members of the support andbetween these bearing members 13. The bearing members 13 have lug-likeextensions 16 on their upper edges which engage holes '17 providedtherefor in the top support member. These features are clearlyillustrated in FIGS. 6 to 9 inclusive.

The worm shaft 15 is provided with a socket 18 for the operating crank19 which may, if desired, be secured in the socket as by means of thescrew 20. The upset portions 3 of the base member provide supports forthe arms 21 which are desirably formed as stampings land have enlargedpontions at their inner ends provided with toothed segments 22 coaotingwith the worm. These arms are swingably mounted on the members It) andare supportedly and swingably disposed between the top and base membersof the support. The relationship of these parts is clearly illustratedin FIGS. 6 and 7.

The arms 21 have angularly disposed upwardly projecting outer endportions 23 having openings 24 therein adapted to receive the reducedportions of the pivots 25 which connect the links 26 to the farms. Thelinks 26 have laterally projecting outer end pontions 37 which terminatein the angularly disposed end portions 27 which are angled to correspondto the angularly disposed end portions 23 of the arms 21 and areprovided with pivot holes 28 for the pivots 25 carried by the arms, seeFIG. 5. These pivots 25 are shouldered so that in assembling the armsand links are not clamped together when the pivots are upset at 29, seeFIGS. 3, 4, and 5. The links 26 are connected to the sash attachingbracket 30 which is provided with longitudinally spaced sets of hingeknuckles 31 adapted to receive the hinge pins 32 which connect thecoupling members 33 to the bracket, the coupling members havinginterengaging hinging pin receiving knuckles thereon. The links aredetachably secured to the coupling members 33 by means of the pivots 34which are desirably of the springable or snap fastener type illusirated.These pivots 34 are secured to the coupling members 33 by means of theclamping ears 35, see FIG. 12. The links 26 are provided with holes 36which have snapon engagement with these springable pivots 34.

The laterally projecting end portions 37 in the links 26 result inseveral advantages, among them being that they permit the links and thearms being collapsed into substantially parallel and in partiallyoverlapping relation as is illustrated in FIG. 3. Also, when the crankis operated to open the sash there is a direct application of forcethrough the offsets 37 which is highly effective, that is, there isleverage action and even a sash which has adhered thereto by paint maybe frictionally engaged with frame pants or the leverage is such thatthe window may be forced open and this without damage to the mechanism.

The actuating arms 21 are relatively thick as compared to the links 26as is illustrated in FIG. 5, so the arms do not bend under 'any ordinarystress. The links are designedly relatively flexible and that isdesirable because the bottom of the sash or other closure raises as itis swung outwardly. The pivotal connection for the links with the sashavoids subjecting the connecting pivots to any undue stress.

The offsets 37 and the links 26 permit the links and arms to collapseinto partially overlapping relation as illustrated in FIG. 3, and withthe sash attaching member 30 in parallel relation to the links and arms.This not only provides for compact collapsing but it insures effectiveoperation from the collapsed position. The upturned or upwardly inclinedouter ends of the arms 21 and the corresponding angular ends of thelinks 26 permit the upward swinging of the sash when it moves outwardlywithout substantial stress on the pivots. This also readily adapts thestructure to installation in which the windows are supported so the topmoves or swings downwardly as the (window is opened. The detachableconnections for the links to the sash is of advantage in that it permitsmanipulation of the window for washing, fior example, as well as beingan advantage in assembling and installing.

In the accompanying drawing we have illustrated our invention asembodied in a window of this type comprising a frame 39, the windowbeing hinged to the top of the casing at 40.

The details of the frame form no part of the invention and are,therefore, not described. The window illustrated is of a well-known andwidely used type. The sash attaohing bracket 30 is adapted to receive aplurality of attaching screws at 41 and is positioned on the inner sideof the bottom rail of the sash. The operator is desirably assembled as aunit and may be readily attached in operative relation to the windowsill or other portion of the frame, and the bracket attached to the sashor other part operated. However, if desired the links may be readilydisengaged from the pivot studs 34 to facilitate installation orcleaning of the window, and reengage therewith as occasion may require.

The parts of the operator of the invention may be very economicallyproduced and assembled. The structure is simple and compact, and withthe offsets 37 of the links the operator is very compact when the partsare in a retracted position. The operator is very easily operated. Theworm acts or serves as a lock for retaining the parts in their adjustedposition.

We have illustrated and described the invention in a highly practicalembodiment thereof. We have not attempted to illustrate or describeother embodiments or adaptations, as it is believed that this disclosurewill enable those skilled in the art to embody or adapt the invention asmay be desired.
